T o all whom t may concern.'

Be it known that I, DAVID S. KENNEDY, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in TypographicalCoinposing-Machines, of which the following is a specification,reference being had therein to the accompanying drawing, being adivision of original application led May 22, 1916, ser. No. 99,059.

- My invention relates to typographical machines, such as linotypemachines of the general organization represented in Letters Patent ofthe United States to O. Mergen-v thaler, No. 436,532, whereincirculating matrices under the action of escapements are released from amagazine in the order in which 'their chanacters are to appear in printand then assembled in line, the! line -transferred to the face of amold, the mold filled with molten metal to form a slug orlinotypeagainst the matrices which produce the type characters thereon,and the matrices thereafter elevated and returned througha distributinmechanism to the magazine from whic they started.v

The present invention is directed to ycertain improvements in theescapement operating devices, as will be more fully pointed out in thedetailed description to follow.

In the accompanying drawing, for the sake of simplicity, I have shown myimprovements in connection with a single magazine only, although it ismy purpose to emlbody them in a machine equipped with a plurality ofmagazines which are movably arranged in such manner that any selectedvone thereof may be brought into operative position at will, such forinstance as illustrated in my pending application Serial No. 99,059,filed May 22, 1916, of which the present application is a division. Itshould be I understood, however, that the invention may ,be embodied inany class of machine to which it is applicable. In addition, I haveshown my invention only in preferred form and by way of example, andobviously many changes and variations may be made therein and in itsmode of application which will still be comprised within its spirit.Generally speaking, I desire it to be understood lthat I do not limitmyself to any specific he drawing is an enlarged vertical sec`V tiontaken through the escapement operat- -ing dev1ces and the magazine withwhich they coperate. v i

The matrices X are stored in the magazine A and pass therefrom into theassembler entrance C under the action of the escapements M mounted infthe supporting frame M1. rIhe frame M1 is provided' with a series ofsliding plungers; N1 by means of which the escapements are rocked in onedirectlon to release the matrices against the action of springs M2 whichvtend constantly to rock them in the Opposite direction. These plungersare actuated by a series or bank of levers N pivoted as at N 2 to afixed part of the machine' frame and operated by vertically movable4reeds N5 reciprocated by powerdriven mechanism under the control of thekeyboard, all in the usual way. Heretofore, andas shown in my priorLetters Patent N o. 1,104,512 the actuating levers for the escapementplungers have been made in substantially L-shape form and have had theirpivots located well to the rear of the forward ends of the magazines. Inthis old arrangment, the parts were subjected to considerable wear asaconsequence of the sliding or wiping engagement between the levers andthe plungers, as well as between the levers and the operating reeds,occurring at each operation. It is the object of the present inventionto avoid this objectionable wear, and to that end I have modified theform and arrangement of the parts in such manner as to reduce the'friction to a minimum.

As shown, the actuating levers N are of considerable length andpractically straight throughout and have their pivotal points located inan inclined plane disposed substantially at right angles to themagazine, (and consequently at right angles to the escapement plungersN1) and passing through the point of engagement of the actuating leverswith the escapement plungers. As a result of this arrangement, when theactuating levers are rocked about their pivots, (as shown by the dottedlines) their upper ends will describe an arc to which the longitudes ofthe escapement plungers are tangent, and the circular measure of sucharc will be substantially equal to the sine of the angle of rotation; ormore generally speaking, the upper ends of the actuating levers willmove practically in a straight line which coincides with thelongitudinal aXes of the escapement plungers, thereby avoiding anyappreciable sliding or wiping engagement between these parts. The leversN are slightly voffset near their middle,

as at N3, to avoid interference` with the vertical mdvement of themagazine and are Y parts when operated.

As before stated, I have shown my improvements merely in their preferredformY and by way of example, and as applied to a particular kind ofmachine, but obviously many modifications and alterations therein and intheir Inode of application will suggest themselves to those skilled inthe art without departure from its scope.

Having thus described my invention, its construction and mode ofoperation, what I claim and desire to secure by Letters Pat'- ent of theUnited States is as follows:

l. In a 'typographical composing machine, the combination of amatrix-releasing escapement, and operating means therefor, the saidmeans including a sliding plunger connected to the escapement, and vapivoted actuating lever of relatively great length and arranged with itsupper end in position to engage said plunger and having its pivotalpoint located in a plane extending substantially at right angles to theplunger and passing through the pointof engagement of the lever with theplunger, said pivotal point being positioned a relatively remotedistance from the escapement-plunger so that inthe pivotal motions ofthe lever, its upper end will describe an arc to which the longitude ofthe plunger is tangent, and the circular measure of which are will besubstantially equal to the sine of the angle of rotation, whereby wearfrom sliding of thelever on the plunger is prevented. Y

2. Inv atypographical machine, the combination of a magazine, a seriesof escape'-- m ments therefor, and means for operating the escapements,the said means including sliding plungers connected to the escape`ments, actuating levers arranged with their' upper ends in position toengage the plungers, and devices to operate the actuating levers, thesaid devicesbei-ng shiftably mounted and interlocked at their upper endswith the actuatinglevers so asto-rock there- ,y n

with.

3. In a typographical machine', the combi'- nation of a magazine,aseries of escapements therefor, and-meansfor operating the escapements,the said means comprising a series of operating devices and an interme#diate series of pivoted levers through which the movement of theoperating devices is imparted to the escapements, the said del-1 vicesbeing shiftablyarranged and interlocked at their upper ends with the`pivoted levers so as to rock therewith. Y

In testimony whereof, I signature hereto.
